Summary

Citytelecom LLC

Russian Federation · AI-generated

residential isp saint-petersburg russia

DATAHOUSE-SPB is operated by Citytelecom LLC, a regional internet service provider based in Saint Petersburg.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as 31-28-3-64.dyn-pool.spb.citytelecom.ru and netnames like FILANCO-NET-31-3 and RU-CITYTELECOM1-20090501.
  • The AS announces 1536 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes are listed as Filanco Network Operations Center and Citytelecom LLC, indicating that the address space is managed under the Filanco administrative group.
  • The inventory consists of six distinct /24 IPv4 blocks and a single /32 IPv6 prefix, representing a modest footprint typical of a regional ISP.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
